A method for transmitting a channel state by a terminal in a communication system, according to one embodiment, comprises the steps of: receiving discontinuous reception (DRX) configuration information from a base station; determining whether the terminal is set to transmit channel state information only in onDuration according to a DRX operation; determining whether an arbitrary subframe to be received is a subframe included in onDuration if the terminal is set to transmit the channel state information only in onDuration according to the configuration; and not transmitting the channel state information on the arbitrary subframe if the arbitrary subframe is not a subframe included in onDuration. According to the embodiment, the terminal can efficiently report channel state information.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, a control message including interruption information, the interruption information indicating whether the UE is allowed to cause an interruption to a serving cell; identifying whether a measurement cycle for a deactivated secondary cell (SCell) is less than a predetermined value; and determining whether the interruption to the serving cell is allowed based on the interruption information and the identification result in a case that the UE performs a measurement of the deactivated SCell.
2. The method according to claim 1 , further comprising: allowing the interruption to the serving cell based on the interruption information being set to a first value and the identification result; and not allowing the interruption to the serving cell based on the interruption information being set to a second value and the identification result.
3. The method according to claim 1 , wherein the interruption to the serving cell is associated with not performing at least one of a preamble transmission for the serving cell, a physical uplink control channel (PUCCH) transmission for the serving cell, a physical hybrid ARQ indicator channel (PHICH) reception for the serving cell, a physical uplink shared channel (PUSCH) transmission for the serving cell, and a sounding reference signal (SRS) transmission for the serving cell.
4. The method according to claim 1 , further comprising: transmitting, to the base station, UE capability information associated with the interruption to the serving cell.
5. A method by a base station in a wireless communication system, the method comprising: generating a control message including interruption information, the interruption information indicating whether a user equipment (UE) is allowed to cause an interruption to a serving cell; and transmitting, to the UE, the control message including the interruption information, wherein a measurement cycle for a deactivated secondary cell (SCell) is compared to a predetermined value by the UE, and wherein it is determined whether the interruption to the serving cell is allowed based on the interruption information and the comparison result in a case that the UE performs a measurement of the deactivated SCell.
6. The method according to claim 5 , wherein the interruption to the serving cell is allowed to be caused, based on the interruption information being set to a first value and the comparison result; and wherein the interruption to the serving cell is not allowed to be caused, based on the interruption information being set to a second value and the comparison result.
7. The method according to claim 5 , wherein the interruption to the serving cell is associated with not performing at least one of a preamble transmission for the serving cell, a physical uplink control channel (PUCCH) transmission for the serving cell, a physical hybrid ARQ indicator channel (PHICH) reception for the serving cell, a physical uplink shared channel (PUSCH) transmission for the serving cell, and a sounding reference signal (SRS) transmission for the serving cell.
8. The method according to claim 5 , further comprising: receiving, from the UE, UE capability information associated with the interruption to the serving cell.
9. A user equipment (UE) in a wireless communication system, the UE comprising: a transceiver; and a controller coupled with the transceiver and configured to control to: receive, from a base station, a control message including interruption information, the interruption information indicating whether the UE is allowed to cause an interruption to a serving cell, identify whether a measurement cycle for a deactivated secondary cell (SCell) is less than a predetermined value, and determine whether the interruption to the serving cell is allowed based on the interruption information and the identification result in a case that the UE performs a measurement of the deactivated SCell.
10. The UE according to claim 9 , wherein the controller is configured to allow the interruption to the serving cell based on the interruption information being set to a first value and the identification result, and wherein the controller is configured to not allow the interruption to the serving cell based on the interruption information being set to a second value and the identification result.
11. The UE according to claim 9 , wherein the interruption to the serving cell is associated with not performing at least one of a preamble transmission for the serving cell, a physical uplink control channel (PUCCH) transmission for the serving cell, a physical hybrid ARQ indicator channel (PHICH) reception for the serving cell, a physical uplink shared channel (PUSCH) transmission for the serving cell, and a sounding reference signal (SRS) transmission for the serving cell.
12. The UE according to claim 9 , wherein the controller is configured to transmit, to the base station, UE capability information associated with the interruption to the serving cell.
13. A base station in a wireless communication system, the base station comprising: a transceiver; and a controller coupled with the transceiver and configured to: control to generate a control message including interruption information, the interruption information indicating whether a user equipment (UE) is allowed to cause an interruption to a serving cell, and transmit, to the UE, the control message including the interruption information, wherein a measurement cycle for a deactivated secondary cell (SCell) is compared to a predetermined value by the UE, and wherein it is determined whether the interruption to the serving cell is allowed based on the interruption information and the comparison result in a case that the UE performs a measurement of the deactivated SCell.
14. The base station according to claim 13 , wherein the interruption to the serving cell is allowed to be caused, based on the interruption information being set to a first value and the comparison result; and wherein the interruption to the serving cell is not allowed to be caused, based on the interruption information being set to a second value and the comparison result.
15. The base station according to claim 13 , wherein the interruption to the serving cell is associated with not performing at least one of a preamble transmission for the serving cell, a physical uplink control channel (PUCCH) transmission for the serving cell, a physical hybrid ARQ indicator channel (PHICH) reception for the serving cell, a physical uplink shared channel (PUSCH) transmission for the serving cell, and a sounding reference signal (SRS) transmission for the serving cell.
16. The base station according to claim 13 , wherein the controller is configured to receive, from the UE, UE capability information associated with the interruption to the serving cell.
